President Obama's perpetual apology tour made a high-profile stop in Cuba last week, and the results have been predictably regrettable. While the world mourned after yet another radical Islamic terror attack, Obama publicly agreed with communist dictator Raul Castro about the United States' supposed failures, caught a baseball game, and danced the tango in Argentina. Now, Raul's older brother, murderous tyrant Fidel Castro, has penned a letter mocking Obama.

In a piece called "El hermano Obama," Castro paid Obama back for his visit by lecturing him on his ignorance of history, and giving the "modest suggestion" that from here on out he just "reflect and do not try now to develop theories about Cuban politics."

"Native populations do not exist at all in the minds of Obama," Castro wrote. "Nor does he say that racial discrimination was swept away by the Revolution; that retirement and salary of all Cubans were enacted by this before Mr. Barack Obama was 10 years old."

After condemning America for its 1961 Bay of Pigs Invasion, the former dictator said Obama also had his South African apartheid history wrong. Cuba's goal, he explained, was not to rid the country of nuclear weapons, "but to help the people of Angola, Mozambique, Guinea Bissau and other fascist colonial rule of Portugal." America and Israel, said Castro, helped "racist South Africa."

As for Obama's attempt to empower the communist Cuban government by improving the country's economy through open trade with the U.S., Castro said, "we don't need the empire to give us any presents."

"No one should pretend that the people of this noble and selfless country will renounce its glory and its rights," wrote Castro. "We are capable of producing the food and material wealth that we need with with work and intelligence of our people."

During his visit to Argentina after his Cuba tour, President Obama explained his opinion on the difference between capitalism and communism, essentially agreeing with Castro that a communist or socialist country did not really need capitalism, but just should do "what works."
